3.1.2.1. Determining RPMs To Install

Determining which RPMs to install is based on the following criteria:

• The lock manager Red Hat Cluster Suite is using — either DLM or GULM

• The Red Hat Cluster Suite and Red Hat GFS functions you are using (besides the standard functions)

• Whether to include development libraries

• The type of kernel (or kernels) is installed

Use the following tables for determining which RPMs to install:

• Table 3-1 — For Red Hat Cluster Suite with DLM

• Table 3-2 — For Red Hat Cluster Suite with GULM

• Table 3-3 — For Red Hat GFS

The tables contain the following information to assist you in determining which packages to install:

• RPMs — The names of the RPMs (excluding revision numbers)

• Inclusion — The tables provide the following information about whether an RPM should be included in the installation:

  • Req: Required RPM — You must install the RPM.

  • Opt: Optional RPM — Refer to the "Purpose" for more information about determining whether to include the RPM.

  • Dev: Development RPM — Used for development purposes. Refer to the "Purpose" for more information about determining whether to include the RPM.

• Purpose — Provides a concise description of the RPM purpose. Assists in determining which RPMs to include other than the required RPMs.

To determine which RPMs to include in the installation, perform the following steps:

1. Determine whether you are installing Red Hat Cluster Suite with DLM or Red Hat Cluster Suite with GULM.

   1. If you are installing Red Hat Cluster Suite with DLM, refer to Table 3-1 to identify which RPMs are required, optional, and for development.

   2. If you are installing Red Hat Cluster Suite with GULM, refer to Table 3-2 to identify which RPMs are required, optional, and for development.

2. If you are installing Red Hat GFS, refer to Table 3-3 to identify which RPMs are required, optional, and for development.

3. With the information gathered in the previous steps, proceed to install the RPMs using the procedures in Section 3.1.2.2 Installing Packages with the rpm Utility.

3.1.2.2. Installing Packages with the rpm Utility

You can use the rpm utility to install RPMs from CDs created with RHN ISOs. The procedure consists of copying RPMs to a local computer, removing the RPMs that are not needed for the installation, copying the RPMs to the cluster nodes, and installing them.

To install the RPMs, follow these instructions:

1. At a local computer (one that is not part of the cluster) make a temporary directory to contain the RPMs. For example:

   $ mkdir /tmp/RPMS/

2. Insert the Red Hat Cluster Suite CD into the CD-ROM drive.

   	Note
   	If a Question dialog box is displayed that asks if you want to run autorun, click No.

3. Copy all the RPM files from the CD (located in /media/cdrom/RedHat/RPMS/) to the temporary directory created earlier. For example:

   $ cp /media/cdrom/RedHat/RPMS/*.rpm /tmp/RPMS/

   	Note
   	If your local computer is running a version of Red Hat Enterprise Linux that is earlier than Red Hat Enterprise Linux 4, the path to the RPMs on the CD may be different. For example, on Red Hat Enterprise Linux 3, the path is /mnt/cdrom/RedHat/RPMS/.

4. Eject the CD from the CD-ROM drive.

5. (Optional) If you are installing Red Hat GFS, insert a Red Hat GFS CD into the CD-ROM drive. If you are not installing Red Hat GFS, proceed to step 8.

   	Note
   	If a Question dialog box is displayed that asks if you want to run autorun, click No.

6. Copy all the RPM files from the CD (located in /media/cdrom/RedHat/RPMS/) to the temporary directory created earlier. For example:

   $ cp /media/cdrom/RedHat/RPMS/*.rpm /tmp/RPMS/

   	Note
   	If your local computer is running a version of Red Hat Enterprise Linux that is earlier than Red Hat Enterprise Linux 4, the path to the RPMs on the CD may be different. For example, on Red Hat Enterprise Linux 3, the path is /mnt/cdrom/RedHat/RPMS/.

7. Eject the CD from the CD-ROM drive.

8. Change to the temporary directory containing the copied RPM files. For example:

   $ cd /tmp/RPMS/

9. Remove the "-kernel" RPMs for kernels that are not installed in the cluster node, and any other RPMs that are not being installed (for example, optional or development RPMS). The following example removes SMP and hugemem "-kernel" RPM files:

   $ rm *-kernel-smp* *-kernel-hugemem*

   For information about selecting the RPMs to install, refer to Section 3.1.2.1 Determining RPMs To Install.

10. Log in to each cluster node as the root user and make a directory to contain the RPMs. For example:

    # mkdir /tmp/node-RPMS/

11. Copy the RPMs from the temporary directory in the local computer to directories in the cluster nodes using the scp command. For example, to copy the RPMs to node rhcs-node-01, run the following command at the local computer:

    $ scp /tmp/RPMS/*.rpm root@rhcs-node-01:/tmp/node-RPMS/

12. At each node (logged in as root), change to the temporary directory created earlier (/tmp/node-RPMS) and install the RPMs by running the rpm utility as follows:

    # cd /tmp/node-RPMS/ # rpm -Uvh *
